ROOFERS MOP HANDLE.

Application filed January 31, 1928. Serial .No. 250,872.

This invention relates to a mop handle for holding yarn or other suitable fibrous mops for the purpose of spreading tar,pitch and the like upon roofs or similar surfaces. In previous constructions the yarn has been fastened to a handle in such a way that it begins to pull out after a relatively short period of use.

The present invention provides a construction by which the mass of yarn may be quickly and firmly aifixed to the handle and will be prevented from becoming loose so that it may be used continuously until the yarn is practically worn out.

The handle is also adapted to hold other types of materials and may be employed in connection with mops intended for other purposes. Details of the invention will be apparent from the following description and set forth in the appended claims.

In the drawings:

Figure 1 is a perspective view of the mop in use.

Figure 2 is a side view of the handle.

Figure 3 is a top plan View of Figure 2.

The handle may be formed of two pieces of wood 1 and 2 of suitablelength, which are grooved on their meeting faces so as to form a central tubular opening 3 extending lengthwise thereof. The two parts are held together by means of bolts 4 near one end thereof and screws 5 near the other end. Other equivalent forms of fastening may also be employed. Moreover, it is obvious that the handle may be made in a single piece with the opening 3 bored therethrough.

A piece of strap iron 6 has one end fastened to the handle by the bolts 4 and the portion extending beyond the handle is bent into an approximately semi-circular bend 7 the material then being bent back upon itself in a return portion 8 which extends downwardly and is given another sharp bend 9, after which the other end of this strap terminates in a portion 10 which lies in contact with the portion 6 and is held in position by one or more of the bolts 4.

The portions 7 and 8 are cut out to form two spaced fingers 19.

At the bend 9 the two portions contact for a short distance and provide a bearing for a pivot pin 11. Pivoted on this pin is an other strap member 12 of general semi-circular form, the other end of which terminates in two spaced fingres 13.

The rod 14 extends through the tubular bore 3 and at one end is provided with a T-head 15 which engages the fingers 13 as clearly shown in the drawing. The opposite end of the rod 14 is screw threaded for a portion of its length as indicated at 16 and provided with a wing nut 17.

A metal cap 18 may be employed and will fit over the end of the wooden handle and be held in position by the bolts 4. This metal cap is provided with an opening for the passage of the rod 14. The purpose of the cap is primarily to prevent the entrance of pitch, tar and the like into the bore 3. I

When it is desired to attach the yarn or other mop material to the mop, the wing nut 17 is turned outwardly so that the rod 14 may be moved endwise and permit the member 12 to take up the full line position shown in Figure 2. The fingers 13 may then be released entirely from the T.-head 15 if desired and the mop material placed in proper position. The T-head 15 is then engaged with the fingers 13 and the nut 17 is screwed on the rod thereby drawing the same lengthwise through the handle and moving the clamping member 12 to the dotted line position of Figure 2. It will be noted that in this position the yarn is held firmly against any removal.

It will .be obvious that this handle provides a very simple and eflicient mechanism for holding the mop material firmly in desired position, while at the same time it permits quick removal and replacement of the material whenever this is desired. Various details of the construction may be used without in any way departing from the spirit of the invention which is to be regarded as limited only by the scope of the appended claims.

I claim as my invention:

1. In a mop, the combination with a handle, of mop clamps located at one end of the handle, one of the clamps being fixed to the handle, and the other being pivoted to the first for movement towards and from it, a rod adapted tobe connected to the movable clamp and extending longitudinally through and beyond the opposite end of the handle, and means cooperating with the extended portion of the rod, and withthe handle to move the rod to swing the movable clamp towards and from the fixed clamp.

and a clamping nut on said threaded portion of the rod for cooperation with the adjacent end of the handle to adjust the movable clamp towards and from the fixed clamp.

In testimony whereof, I have hereunto subscribed my name.

ROBERT E. CALLEN.
